Specific Applications & Hydraulic Circuit Routing
Part OFL1 Series fittings provide reliable fluid power conveyance in demanding mobile and stationary equipment circuits:
- High-Flow Pump & Motor Outlets: Large-bore fluid conveyance on main pump manifolds, hydraulic motors, and industrial power units utilizing Part OFL1 Series.
- Severe Shock & Pressure Pulsation: Distributes mechanical clamping force across four high-tensile bolts to eliminate fitting fatigue and leakage.
- Heavy Equipment Hydraulic Mainlines: Heavy construction, marine winches, and industrial presses requiring robust 4-bolt flange interfaces.
Installation & Assembly Guidance
- Flange Face & O-Ring Seating: Verify the captive O-ring is lightly lubricated and seated cleanly in the flange head groove.
- Cross-Pattern Bolt Tightening: Snug all four Grade 8 / 10.9 bolts finger-tight, then tighten progressively in a diagonal crossover pattern.
- Torque Specification Adherence: Torque bolts evenly to SAE J518 specifications to ensure parallel clamping without cocking the flange halves.
- Inspection & Retorque: Check split flange gap clearance to ensure equal spacing between clamp halves and port face.
